Nutritionists call omega-3 and omega-6 fatty acids “essential” fats for good reason.
The human body needs them for many functions, from building healthy cells to maintaining brain and nerve function.
Our bodies can’t produce them. The only source is food.

These polyunsaturated fats are important for another reason.
There’s growing evidence that they help lower the risk of heart disease.
Some studies suggest these fats may also protect against type 2 diabetes, Alzheimer’s disease, and age-related brain decline.
